What the Pentium Dual-Core T4400 is
The Intel Pentium Dual-Core T4400 is a dual core Penryn mobile processor from December 2009 for budget notebooks. It runs two cores at 2.2 GHz with no turbo and no Hyper-Threading, so 2 cores give 2 threads. Cache is 1 MB of shared L2 on a 45 nm process. Power is rated at 35 W with an 800 MT/s front side bus.
The T4400 adds 100 MHz over the T4300 at the same 35 W. Against the T4500 it trails by 100 MHz. Family tables place it in the T4xxx line with Socket P.
There is no graphics on the CPU. Display comes from the mobile chipset.
Socket and motherboard compatibility
The Pentium Dual-Core T4400 fits Socket P with 478 pins. Montevina boards boot it directly with a late 2009 BIOS.
The Socket vs chipset: what decides whether a CPU works guide covers pairing rules, and the Intel Pentium Dual-Core T4500 page shows a faster Pentium on the same socket.
Memory, PCIe and cooling
Memory is DDR2 or DDR3 in two channels depending on the chipset.
The 800 MT/s front side bus links the CPU to the chipset. PCIe slots hang off the chipset.
Cooling uses the notebook vendor heat pipe assembly rated for 35 W.
Upgrade paths
On Socket P the upgrade is the T4500 on the same board. Beyond Socket P a move to Arrandale needs a new notebook.
